*About HPT604 Level Sensor

HPT604 is a submersible level pressure sensor suitable for liquid level or pressure and depth measurement. It made of 316 SS housing. Each submersible pressure transducer features a removable nose cone at the sensor which protects the diaphragm from damage.Ventilation tube in the cable automatically compensates for changes in atmospheric pressure above the tank. The HPT604 Submersible Liquid Level Transmitter can be used to measure water level; well depth; groundwater level; bore well, underground water, river etc,.
